PATENT HEINRICH GONZLER AND ARNOLD MORE, 01 ELBERFELD, GERMANY, ASSIGNORS, BY MESNE ASSIGNMENTS, T WINTHROP CHEMIGAL COMPANY, INC., 0]! NEW YORK,

N. Y., A CORPORATION OF NEW YORK rnocnss or PREPARING rnniwn MERGURIG ACETATE No Drawing. Application filed October 21, 1929, Serial No. 401,378, and in Germany October 80, 1 928.

The present invention relates to a process 7 of preparing phenyl-mercuric acetates, more particularly preparing of the'compound of the probable formula:

5 e 11,. Hg. 0. 00.0118,

According to our invention phenyl-mercuric acetate is prepared by heating-benzene with mercuric oxide and glacial acetic 10 acid. Instead of mercuric oxide there may ing equivalent to mercuric oxide for the purpose of the invention. The quantities of the three components reacting with each other may be varied within the widest limits, but generally we are using a large excess of benzene and of glacial acetic acid, say an excess of 10-100 fold of the theory. The temperatures required range between about 60 C. and the boiling point of the reaction mixture, and the reaction is complete after heating for several hours, say 3-10 hours.

The invention is illustrated by thefollowand the boiling point of the mixture for several hours.

2. The process which comprises heating 7 one molecular quantity of mercuric oxide 40 with about 10-100 molecular quantities of benzene and of glacial acetic acid between about C. and the boiling point of the mixture for about several hours.v

3. The process which comprises boiling 45 under reflux for-about 2-3 hours a mixture be used mercuric acetate, this compound besolid of about one molecular quantity of mercuric OFFICE j oxide, 10-100 molecular quantities of benzene and 10-100 molecular quantities of. glacial acetic acid. I y g In te'stlmony whereof, weifix our signatures.
